Abstract
OBJECTIVES To cross-culturally adapt and validate a Spanish version of the Exercise-Induced Leg Pain questionnaire. DESIGN Clinical measurement study. PARTICIPANTS The validity and reliability of the adapted version were assessed in four groups of 40 patients with exercise-induced leg pain, 40 physically active healthy individuals (control group), 40 athletes with other leg conditions and 40 athletes, military personnel and candidates with no history of injury (risk group). MAIN MEASURE Exercise-Induced Leg Pain questionnaire. REFERENCE MEASURES Spanish version of the Short-Form 36 and Schepsis postsurgical classification scale. RESULTS In patients with exercise-induced leg pain, the mean age was 24.9 (± 6.7) years and the mean score of the questionnaire was 62.8 (± 10.9). The standard error of measurement and minimum detectable change threshold were 1.67 and 4.63 points, respectively. Excellent internal consistency (Cronbach's α = 0.942) and test-retest reliability (intraclass correlation coefficient = 0.995) were found. The exploratory and confirmatory factor analyses indicated that a one-factor solution explained 66.84% of the variance. For construct validity, 87.5% of the previously stated hypotheses were fulfilled between the total score of the questionnaire and Short-Form 36 dimensions. Concurrent validity, assessed by the Schepsis scale, was almost perfect (r = 0.92, p < 0.001). The predictive validity of the questionnaire was demonstrated using the receiving operating curve (area of 0.992; 95% CI: 0.983-1, p < 0.001). CONCLUSION The Spanish version of the Exercise-Induced Leg Pain questionnaire resulted in a reliable and valid instrument to assess patients with exercise-induced leg pain.

Microdialysis for chronic exertional compartment syndrome: a pilot study. BMC Sports Sci Med Rehabil 2021; 13:21. [PMID: 33673874 PMCID: PMC7934517 DOI: 10.1186/s13102-021-00245-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2020] [Accepted: 02/17/2021] [Indexed: 11/30/2022]
Abstract
Background Diagnosing chronic exertional compartment syndrome (CECS) is still a challenge. An increase in intramuscular pressure during and following exercise is accepted as the diagnostic standard. However, neither the methods used nor the interpretation of the obtained results are sufficiently standardized. Methods In the present pilot study, the metabolic state of CECS patients was investigated using microdialysis. We hypothesized that there was no difference in intramuscular concentrations of glucose, lactate, glutamate, and glycerol before and after exercise (H10) or between patients suffering from CECS and healthy control subjects (H20). This study was designed as an explorative case-control study (level of evidence III). Twelve patients suffering from CECS of the lower leg and six matched asymptomatic control subjects underwent microdialysis in the anterior (n = 7) or deep posterior compartment (n = 11) of the leg. Following ultrasound-guided insertion of the microdialysis catheters, 10-minute fractions of the dialysates were collected first during rest and then following fatigue- or pain-induced discontinuation of exercise. Dialysates were analysed for lactate, glucose, glutamate, and glycerol concentrations 6 × 10 min before and 6 × 10 min after exercise. Results Exercise-induced increases in lactate, glutamate, and glycerol concentrations were detected in both CECS patients and control subjects (all p < 0.001). No differences between CECS patients and control subjects were found by comparing the intramuscular glucose, lactate, glutamate, and glycerol concentrations at rest and following exercise (all p > 0.05). Conclusions We found exercise-induced increases in the lactate, glutamate, and glycerol levels in skeletal muscle. However, the metabolic changes did not differentiate CECS patients from healthy subjects. Trial registration The registration trial number is DRKS00021589 on DRKS. ‘Retrospectively registered’. Date of registration: April 4, 2020.

Historical ESWT Paradigms Are Overcome: A Narrative Review. BIOMED RESEARCH INTERNATIONAL 2016; 2016:3850461. [PMID: 27493955 PMCID: PMC4967434 DOI: 10.1155/2016/3850461] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/21/2016] [Revised: 05/17/2016] [Accepted: 06/13/2016] [Indexed: 11/17/2022]
Abstract
Extracorporeal Shock Wave Therapy (ESWT) is a conservative treatment modality with still growing interest in musculoskeletal disorders. This narrative review aims to present an overview covering 20-year development in the field of musculoskeletal ESWT. Eight historical paradigms have been identified and put under question from a current perspective: energy intensity, focus size, anesthesia, imaging, growth plates, acuteness, calcifications, and number of sessions. All paradigms as set in a historical consensus meeting in 1995 are to be revised. First, modern musculoskeletal ESWT is divided into focused and radial technology and the physical differences are about 100-fold with respect to the applied energy. Most lesions to be treated are easy to reach and clinical focusing plays a major role today. Lesion size is no longer a matter of concern. With the exception of nonunion fractures full, regional, or even local anesthesia is not helpful in musculoskeletal indications. Juvenile patients can also effectively be treated without risk of epiphyseal damage. Further research is needed to answer the question about if and which acute injuries can be managed effectively. Treatment parameters like the number of sessions are still relying on empirical data and have to be further elucidated.

Abstract
Background The purpose of this systematic review is to analyse the results of operative treatment for midportion Achilles tendinopathy and to provide evidence based recommendation for the indication of the individual published techniques. Methods MEDLINE, Cochrane Database, ISI Web of Knowledge and Google databases (1945 till September 2014) were electronically searched. The quality of the included articles was evaluated using the Coleman Methodology Score. Success rates, patient satisfaction, and the complication rates were determined. Results Twenty studies met our inclusion criteria. A total of 801 tendons were treated in 714 patients with open or minimally invasive techniques. The mean success rate was 83.4 %. Complications were reported in 6.3 % of the cases. The articles on minimally invasive techniques and open procedures reported on an average success rate of 83.6 % and 78.9 (p = 0.987). Patient satisfaction rates for minimally invasive techniques and open procedures were 78.5 % and 78.1 % (p = 0.211). The complication rate was 5.3 % for the minimally invasive techniques and 10.5 % for the open procedures (p = 0.053). Conclusion We conclude that success rates of minimally invasive and open treatments are not different and that there is no difference in patient satisfaction but there is a tendency for more complications to occur in open procedures.

Abstract
Background The objective measurement of the mechanical component and its role in chronic ankle instability is still a matter of scientific debate. We analyzed known group and diagnostic validity of our ankle arthrometer. Additionally, functional aspects of chronic ankle instability were evaluated in relation to anterior talar drawer. Methods By manual stress testing, 41 functionally unstable ankles were divided as mechanically stable (n = 15) or mechanically unstable (n = 26). Ankle laxity was quantified using an ankle arthrometer. Stiffness values from the load displacement curves were calculated between 40 and 60 N. Known group validity and eta2 were established by comparing manual and arthrometer testing results. Diagnostic validity for the ankle arthrometer was determined by a 2 × 2 contingency table. The functional ankle instability severity was quantified by the German version of the Foot and Ankle Ability Measure (FAAM-G). Stiffness (40–60 N) and FAAM-G values were correlated. Results Mechanically unstable ankles had lower 40–60 N stiffness values than mechanically stable ankles (p = 0.006 and <0.001). Eta for the relation between manual and arthrometer anterior talar drawer testing was 0.628. With 5.1 N/mm as cut-off value, accuracy, sensitivity, and specificity were 85%, 81%, and 93%, respectively. The correlation between individual 40–60 N arthrometer stiffness values and FAAM-G scores was r = 0.286 and 0.316 (p = 0.07 and 0.04). Conclusions In this investigation, the ankle arthrometer demonstrated a high diagnostic validity for the determination of mechanical ankle instability. A clear interaction between mechanical (ankle arthrometer) and functional (FAAM-G) measures could not be demonstrated.

Abstract
BACKGROUND The results of operative treatment for recalcitrant midportion Achilles tendinopathy and recalcitrant retrocalcaneal bursitis were evaluated using the patient administered, disease specific, and validated VISA-A-G questionnaire. METHODS A cohort of 89 patients was prospectively followed. These patients underwent operations for sport induced midportion Achilles tendinopathy (39 procedures) or retrocalcaneal bursitis (55 procedures). Depending on the individual intraoperative findings the patients of either disease were treated with two respective operative modifications (tendon repair or no tendon repair). Preoperative and follow-up status (3, 6, and 12 months) were investigated using the VISA-A-G questionnaire. RESULTS Preoperatively, the four groups scored from 37.0 ± 17.6 to 45.9 ± 15.2 (p = 0.376-0.993) on the VISA-A-G questionnaire. Six and 12 months postoperatively, the VISA-A-G scores improved significantly (p < 0.001). Twelve months postoperatively, the groups' scores were not different (p = 0.100-0.952) and ranged from 80.8 ± 17.9 to 90.3 ± 10.6. CONCLUSION Retrocalcaneal bursitis and midportion Achilles tendinopathy responded equally well to operative treatment. When repaired, additional tendon lesions did not influence this result. We demand to differentiate not only between midportion Achilles tendinopathy and retrocalcaneal bursitis but also to identify additional Achilles tendon lesions to specifically address these lesions during operative procedures.

Retrocalcaneal bursitis but not Achilles tendinopathy is characterized by increased pressure in the retrocalcaneal bursa. Clin Biomech (Bristol, Avon) 2014; 29:283-8.

Abstract
BACKGROUND We questioned whether different forms of Achilles tendon overuse injuries can be differentiated by retrocalcaneal bursa pressure measurement. METHODS Retrocalcaneal bursa pressure was determined by using invasive pressure measurement in patients suffering from retrocalcaneal bursitis (n=13) or Achilles tendinopathy (n=15), respectively. Standardized measurements were taken with the subject lying prone. Initially, the foot and ankle was in a spontaneous, unsupported position. Then passive dorsiflexion was induced by an increasing pressure which was applied in five defined steps against the plantar forefoot. FINDINGS Mean pressures found in unloaded position were 30.5 (SD 28.9) mmHg in retrocalcaneal bursitis and -9.9 (SD 17.2) mmHg in Achilles tendinopathy (p<0.001). A stepwise increase in passive ankle dorsiflexion was associated with increasing pressure values in both groups. The differences were p=0.009 to 0.035 when dorsiflexion was initiated with 10, 20, 30, and 40N, respectively. Dorsiflexion induced by 50N load resulted in a mean pressure of 113.7 (SD 124.9) mmHg for retrocalcaneal bursitis and 32.5 (SD 48.9) mmHg for Achilles tendinopathy (p=0,051). INTERPRETATION Higher retrocalcaneal bursa pressure values were found in patients suffering from chronic retrocalcaneal bursitis. This result supports the hypothesis that retrocalcaneal bursa hypertension leads to an impingement lesion of the corresponding anterior Achilles tendon.

Abstract
BACKGROUND Despite massive research efforts, it remains unclear how mechanical ankle instability (MAI) and functional ankle instability (FAI) affect joint control in the situation of ankle sprain. Thus, the purpose of this study was to evaluate whether individuals with MAI have deficits in stabilising their ankle joint in a close-to-injury situation compared with those with FAI and healthy controls. METHODS Ankle-joint control was assessed by means of three-dimensional motion analysis and electromyography in participants with FAI and MAI (n=19), in participants with pure FAI (n=9) and in healthy controls (n=18). Close-to-injury situations were simulated during standing, walking and jumping by means of a custom-made tilt platform. RESULTS Individuals with FAI and MAI displayed significantly greater maximum ankle inversion angles (+5°) and inversion velocities (+50°/s) in the walking and jumping conditions compared to those with pure FAI and controls. Furthermore, individuals in the FAI and MAI group showed a significantly decreased pre-activation of the peroneus longus muscle during jumping compared to those with FAI. No differences between groups were found for plantar flexion and internal rotation, or for muscle activities following tilting of the platform. CONCLUSIONS The present study demonstrates that MAI is characterised by impairments of ankle-joint control in close-to-injury situations. This could make these individuals more prone to recurrent ankle sprains, and suggests the need for additional mechanical support such as braces or even surgery. In addition, the study highlights the fact that dynamic experimental test conditions in the acting participant are needed to further unravel the mystery of chronic ankle instability.

Abstract
BACKGROUND Chronic ankle instability (CAI) is a term that is not well defined until now in spite of a large body of respective literature. Most frequently this umbrella term is used synonymously for functional ankle instability and the role of the mechanical component is not fully understood. PATIENTS/MATERIAL AND METHODS In a cohort consisting of 15 patients suffering from CAI we preoperatively investigated the mechanical component using both stress radiographs and ankle arthrometry. The functional impact was measured with the FAAM-G (foot and ankle ability measure, German version). The results were compared with a respective group of 17 uninjured subjects. RESULTS Relevant differences were found between the patients and the uninjured groups in the mechanical (stiffness in the 40 - 60 N region of the load deformation curves and the ratio between stiffness in the 125 - 175 N and 40 - 60 N region) and functional analyses (FAAM-G), respectively (p < 0.001 - 0.040). There was no difference found between groups in the upper (125 - 175 N) region of the load deformation curves. CONCLUSIONS This article helps to clarify the role of the mechanical component in CAI. Patients suffering from both functional and mechanical ankle instability can be detected with the FAAM-G questionnaire and with different ankle stiffness parameters from ankle arthrometer stress testing. These measures differentiate CAI patients from uninjured persons with functionally and mechanically stable ankles. Therefore, these instruments can be recommended to diagnose and quantify the mechanical component in CAI.

Abstract
BACKGROUND Intensive physical load can damage epi-/apophyseal growth. Osgood-Schlatter disease is a well-known and sport-associated overuse injury of the tibial tuberosity apophysis. Long-lasting load-associated pain and a reduced ability to play sports can be the consequence. AIM OF THE STUDY The aim of this study was to analyse the safety and effectiveness of extracorporeal shock wave therapy (ESWT) for recalcitrant Osgood-Schlatter disease. PATIENTS AND METHODS 14 adolescent patients, median age 14 (13.2-14.7) years, suffering from recalcitrant Osgood-Schlatter disease (16 symptomatic knees) were treated with radial extracorporeal shock waves. The nine boys, median age 14 (13.5-15.0) years and the five girls, median age 12 (10.8-15.2) were retrospectively followed up 5.6 (3.4 - 6.7) years later using the disease specific VISA-P-G questionnaire which is validated for jumper's knee. RESULTS At follow up the median VISA-P-G score was 100 (82.9-100.9). Twelve of 16 knees (75%) reached 100 out of 100 VISA-P-G points. Four patients changed their sports activity due to persisting problems at the distal patellar tendon insertion. Four knees had persisting tibial tuberosity pain when playing sport. Pain induced by activities of daily living (stair climbing) was stated in two cases. No side effects or long-term complications were reported. CONCLUSIONS This pilot study demonstrates that radial ESWT is a safe and promising treatment for adolescent athletes with recalcitrant Osgood-Schlatter disease.

Abstract
Up to now diagnosis of Haglund's disease is based on patient's history and clinical findings. There is no valid diagnostic tool described to functionally detect retrocalcaneal bursitis. Retrocalcaneal bursa pressure may be increased in these patients. We hypothesized that retrocalcaneal bursa pressure can directly be measured. In this pilot investigation we tested the feasibility of a system which is already in clinical use for arterial blood pressure monitoring to quantitatively assess retrocalcaneal bursa pressure in a human and a swine cadaver specimen and in vivo. Using the presented system retrocalcaneal bursa pressure measurement is demonstrated to be feasible. Moreover, intrabursal pressure is reproducibly and validly quantified. In an uninjured subject increasing ankle dorsiflexion was not associated with increasing pressure in the retrocalcaneal bursa. Experimental liquid injection in the retrocalcaneal bursa was associated with increased intrabursal pressure and increasing pain. Feasibility of the tested setup could be proven. The question, if retrocalcaneal bursitis can be distinguished from further heel pathologies by different pressures in the retrocalcaneal bursa has to be addressed in a subsequent in vivo study.

Abstract
OBJECTIVE The aim of this study was to compare training effects on postural control using two different unstable shoe constructions. SUBJECTS AND SETTING Twenty-nine healthy subjects participated in this study and were randomly divided into three groups. Two experimental groups (10 subjects in each group) were assigned to a 6 week training program of specific sensorimotor exercises with unstable shoe constructions, one group using MBT(®) shoes and one group wearing Reflex Control(®) shoes (RC). Subjects in the control group (9 subjects) did not perform balance training. MAIN OUTCOME MEASURES Postural control was measured in one-leg stance in two testing conditions. We recorded postural sway on a force plate (static testing situation) and displacements of a moveable platform (dynamic testing situation) before and after the training period. RESULTS There were no effects of training with unstable shoe constructions on postural sway in the static testing condition (for comparison of groups: p = 0.990 and p = 0.119). However, the RC group showed statistically significant improvements in the dynamic testing situation (p = 0.014 compared to control subjects). In the MBT group improvements were not significantly different in comparison to control group (p = 0.518). CONCLUSIONS Our results indicate that exercises using unstable shoe constructions, particularly the RC, improve postural control only in dynamic conditions.

Abstract
BACKGROUND Stress tests are used to diagnose both acute and chronic lateral ankle instability. Commonly used stress tests require radiography and their reliability and sensitivity is still under debate. We developed a non radiographic ankle arthrometer to objectively assess mechanical ankle stability. This device was validated against stress radiographs in a cadaver investigation. MATERIALS AND METHODS Nine cadaver specimens were tested under: 0, 15, and 30 degrees ankle plantarflexion and 50 N, 100 N, 150 N, and 200 N anterior drawer load application. First, intact specimens were tested. Then the anterior talofibular ligament, calcaneofibular ligament and posterior talofibular ligament were sequentially cut. Anterior drawer displacement was analyzed simultaneously by a displacement transducer and by radiographic measurement. Stiffness was calculated as the linear increment of the load deformation curve. Results of a commercially available stress testing device served as a standard. RESULTS Stable and unstable ankles were differentiated by ankle arthrometer displacement and stiffness analyses (p = 0.012 and 0.003) with the arthrometer adjusted to 0 degrees of plantarflexion and 50 N anterior drawer load application. Standardized stress testing device and ankle arthrometer stress radiographic measurements correlated significantly (p = 0.000 to 0.027). Transducer measured anterior drawer instability was highly sensitive (96.3%), while specificity was 44.4%. Setting a cut off value of 4.5 N/mm, the stiffness analyses discriminated stable and unstable ankles with a sensitivity of 91.7% while the specificity was 62.5%. CONCLUSION The ankle arthrometer was able to measure anterior subluxation of the talus in relation to the tibia in a cadaver experiment. The procedure is non-radiographic and highly sensitive in differentiating unstable from stable ankles. CLINICAL RELEVANCE Availablity of a nonradiographic device to measure ankle instability could improve diagnostic accuracy and facilitate decision making in patients with chronic ankle instability.

INTRODUCTION A nonradiographic arthrometer was developed to objectively quantify anterior talar drawer instability in stable and unstable ankles. Diagnostic validity of this device was previously demonstrated in a cadaver study. The aim of the present study was to validate the ankle arthrometer in an in vivo setting. METHODS Twenty-three subjects participated in the study. An orthopedic surgeon first performed a manual anterior talar drawer test to classify the subjects' ankles as stable or unstable. The subjects were then evaluated using the ankle arthrometer, and filled out a validated self-reported questionnaire (German version of the Foot and Ankle Ability Measure [FAAM-G]). Ankle stiffness was calculated from the low linear region (40-60 N) of the load deformation curves obtained from the ankle arthrometer. Reliability testing of these stiffness values was done based on load deformation curves, with 150 and 200 N maximum anterior drawer loads applied in the ankle arthrometer. RESULTS Using the manual anterior drawer test, 16 ankles were classified as stable and 7 were classified as unstable. Arthrometer stiffness analysis differentiated stable from unstable ankles (P = 0.00 and P = 0.01, respectively). Test-retest demonstrated an accurate reliability (intraclass correlation coefficient = 0.80). A significant correlation was found between both FAAM-G subscales and the arthrometer stiffness values (r = 0.43 and 0.54; P = 0.04 and 0.01). Discussion Subjects with and without mechanical ankle instability could be differentiated by ankle arthrometer stiffness analysis and the FAAM-G questionnaire results. This nonradiographic device may be relevant for screening athletes at risk for ankle injuries, for clinical follow-up studies, and implementing preventive strategies. CONCLUSION Validity and reliability of the new ankle arthrometer is demonstrated in a small cohort in an in vivo setting.

Abstract
BACKGROUND The VISA-A questionnaire is currently the only valid, reliable, and disease specific patient administered questionnaire for research in Achilles tendinopathy. To perform multinational and multilingual investigations this instrument was already adapted to several languages. According to the "guidelines for the process of cross-cultural adaptation of self-report measures" we already translated and validated the VISA-A questionnaire for patients with Achilles tendinopathy. AIM OF THE STUDY To cross-culturally adapt and validate the VISA-A Questionnaire for German-speaking patients suffering from Haglund's disease. METHODS The VISA-A-G questionnaire was tested for reliability, validity, and internal consistency in 39 Haglund's disease patients and 79 asymptomatic persons. For concurrent validity the VISA-A-G was compared with the Curwin and Stanish tendon grading system and with the Percy and Conochie classification system for the effect of pain on athletic performance. VISA-A-G results in Haglund's disease were additionally compared with VISA-A-G results obtained from Achilles tendinopathy patients and with VISA-A results presented in the international literature. RESULTS ICC for the VISA-A-G questionnaire in conservatively treated Haglund's disease patients was 0.96. In asymptomatic students and joggers ICC was 0.97 and 0.60. When correlated with the grading system of Curwin and Stanish and with the Percy and Conochie classification rho was -0.95 and 0.94, respectively. Internal consistency (Cronbach's alpha) for the total VISA-A-G scores of the patients was calculated to be 0.87. Compared with VISA-A-G results obtained from Achilles tendinopathy patients there was no relevant difference discernible. Compared with VISA-A results presented in the original publication no difference was found statistically for students, healthy people, conservative, and preoperative patients, respectively. CONCLUSIONS This study confirms that the VISA-A-G is a valid and reliable measure for German-speaking patients suffering from Haglund's disease.

Abstract
BACKGROUND Recent literature shows evidence for effective treatment for plantar fasciitis using either focused or radial shock waves. Up to now no research has been available which compares these different procedures. We hypothesized (H(0) Hypothesis) that for plantar fasciitis, outcomes following focused or radial shock wave treatment were equal. MATERIALS AND METHODS For this pilot study, 39 patients suffering from recalcitrant plantar fasciitis were randomized in two groups. Treatment was performed in three sessions. Once a week 2000 impulses of radial (0.17 mJ/mm(2)) or focused (0.20 mJ/mm(2)) shock waves were applied. Efficacy was determined by multivariate analysis of eight single variables including changes in Foot Functional Index, neuromuscular performance (Single leg drop and long jump, postural stability, isokinetic testing), and by a composite score from baseline to 12 weeks followup. Multivariate Wilcoxon tests (Wei-Lachin procedure) and formal meta-analytic procedure with adjustment for subgroups was performed to determine the adjusted effect sizes with their corresponding confidence intervals. RESULTS The overall result (;;Crude Pooling'') shows ;;small'' superiority of the focused extracorporeal shock wave therapy (MW = 0.55, LB-CI = 0.4644). Adjusted for age the focused treatment exhibited ;;more than small'' superiority (MW = 0.59, LB-CI > 0.5) and this result is statistically significant (LB-CI = 0.5067, benchmark for equality = 0.5). CONCLUSION This study provides some evidence for focused extracorporeal shock wave treatment being superior to radial extracorporeal shock wave therapy for recalcitrant plantar fasciitis.

Abstract
OBJECTIVES The evaluation of health-related quality of life and physical function is important for determining therapeutic strategies following ankle injuries. The Anglo-American Foot and Ankle Ability Measure (FAAM) is a valid and reliable self-reported measure to detect functional deficits in chronic lateral ankle instability. The purpose of this study was to translate, cross-culturally adapt and validate the FAAM questionnaire for use with German-speaking patients with chronic lateral ankle instability. PATIENTS/PARTICIPANTS Preoperative and conservatively treated patients with chronic lateral ankle instability. Sport students and volleyball athletes served as control groups. MAIN OUTCOME MEASUREMENTS The FAAM was forward and back translated, cross-culturally adapted and validated. The study population completed the FAAM-G questionnaire twice within 3-5 days. Additionally, the patients were scored with the Good ankle laxity classification system. Test-Retest reliability, construct validity and internal consistency were calculated. RESULTS Reliability and validity of the FAAM-G were examined in presurgical chronic ankle instability patients (n=24), conservatively treated chronic ankle instability patients (n=17), university sport students (n=31) and volleyballers (n=37). Test-retest reliability revealed fair, good, or excellent reliability (inter-class correlation coefficient (ICC)=0.590-0.998; ρ=0.528-1.000). Construct validity, tested between the FAAM-G subscores and the Good et al ankle laxity classification system demonstrated strong correlations (ρ = -0.819 to -0.861). CONCLUSIONS The original FAAM questionnaire was successfully translated and cross-culturally adapted from English to German. Corresponding to the Anglo-American version, the FAAM-G is a reliable and valid questionnaire for self-reported assessment of pain and disability in German-speaking patients suffering from chronic ankle instability.

Abstract
BACKGROUND Achilles tendinopathy is the predominant overuse injury in runners. To further investigate this overload injury in transverse and longitudinal studies a valid, responsive and reliable outcome measure is demanded. Most questionnaires have been developed for English-speaking populations. This is also true for the VISA-A score, so far representing the only valid, reliable, and disease specific questionnaire for Achilles tendinopathy. To internationally compare research results, to perform multinational studies or to exclude bias originating from subpopulations speaking different languages within one country an equivalent instrument is demanded in different languages. The aim of this study was therefore to cross-cultural adapt and validate the VISA-A questionnaire for German-speaking Achilles tendinopathy patients. METHODS According to the "guidelines for the process of cross-cultural adaptation of self-report measures" the VISA-A score was cross-culturally adapted into German (VISA-A-G) using six steps: Translation, synthesis, back translation, expert committee review, pretesting (n = 77), and appraisal of the adaptation process by an advisory committee determining the adequacy of the cross-cultural adaptation. The resulting VISA-A-G was then subjected to an analysis of reliability, validity, and internal consistency in 30 Achilles tendinopathy patients and 79 asymptomatic people. Concurrent validity was tested against a generic tendon grading system (Percy and Conochie) and against a classification system for the effect of pain on athletic performance (Curwin and Stanish). RESULTS The "advisory committee" determined the VISA-A-G questionnaire as been translated "acceptable". The VISA-A-G questionnaire showed moderate to excellent test-retest reliability (ICC = 0.60 to 0.97). Concurrent validity showed good coherence when correlated with the grading system of Curwin and Stanish (rho = -0.95) and for the Percy and Conochie grade of severity (rho 0.95). Internal consistency (Cronbach's alpha) for the total VISA-A-G scores of the patients was calculated to be 0.737. CONCLUSION The VISA-A questionnaire was successfully cross-cultural adapted and validated for use in German speaking populations. The psychometric properties of the VISA-A-G questionnaire are similar to those of the original English version. It therefore can be recommended as a sufficiently robust tool for future measuring clinical severity of Achilles tendinopathy in German speaking patients.

Abstract
BACKGROUND Manufacturers attribute specific shoes and sole construction to induce neuromuscular training. Thus injury prevention or rehabilitation from injury is aimed. HYPOTHESIS H1=Different shoe and sole construction result in different load to the neuromuscular system and postural control. STUDY DESIGN Controlled laboratory study. METHODS 10 healthy subjects were tested postural stabilization using a force plate and EMG-recordings. First each person performed three 20 sec single leg unshod stance trial (control condition). Then MBT shoe, Finnamic-Rollenschuh and ReflexControl were applied and tested in a randomized order. RESULTS No difference in the EMG- activity was detected comparing the barefoot condition with MBT and Finnamic-Rollenschuh (p=0,051-1,000). However with one exception (barefoot M. gastrocnemius. EMG-activity; p=0,110) putting on the ReflexControl shoe increased the EMG-activity relative to all three tested muscles and shoe/barefoot conditions (p=0,000-0,001). Moreover, the ReflexControl shoe led to a highly significantly higher postural sway (p=0,000-0,072), while MBT, Finnamic-Rollenschuh and barefoot conditions were not statistically different (p=0,818-1,000). CONCLUSIONS This study confirms that during upright stance the ReflexControl shoe is a means for neuromuscular training, while MBT and Finnamic-Rollenschuh simulate barefoot stance.

Abstract
BACKGROUND The dorsolateral calcaneocuboid ligaments have different configurations. In the literature they are only described as either the dorsal or lateral calcaneocuboid ligament. However, recent reconstructive surgical techniques may benefit from a better understanding of the anatomy. The aims of this study were to classify the morphology and attachments of the dorso-lateral calcaneocuboid ligaments and to determine their dimensions. MATERIALS AND METHODS The dorso-lateral aspects of the calcaneocuboid joint of 30 cadaver feet were dissected to expose the associated ligaments. Further, we evaluated possible bony landmarks of the calcaneus that could imply which shape or course the ligament would have in a specific individual. RESULTS Our findings showed a wide variety of configurations in shape, number, and attachment sites. A constant dorsal ligament and an additional narrower lateral ligament was detectable in half of the cases. The majority of the dorso-lateral calcaneocuboid ligament-complex had an upward course and fanning out from proximal to distal. No bony predictor for the ligaments' shape or course was found. CONCLUSION The dorso-lateral ligament-complex of the calcaneocuboid joint revealed a wide variety of configurations. CLINICAL RELEVANCE Better understanding of the anatomy of these ligaments may aid in the anatomic reconstruction of these ligaments.

Abstract
BACKGROUND Stress radiographic measurements play an important role in assessing the degree of joint instability in scientific investigations and for decision making in treatment. However, their validity and reliability are still a matter of intensive debate. HYPOTHESIS There is no difference regarding interobserver and intraobserver reliability with respect to anterior talar drawer, talar tilt, and calcaneocuboid stress radiographs. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 4. METHODS Eighty-nine anterior talar drawer, 89 talar tilt, and 76 calcaneocuboid stress radiographs were selected. Analyses for anterior talar drawer (1 measurement technique), talar tilt (1 measurement technique), and lateral calcaneocuboid instability (4 measurement techniques) were performed by 4 independent raters. One rater repeated the measurements after 1 month. Intraclass and interclass correlation coefficients (ICCs) with calculated confidence intervals assessed intratester and intertester reliability of each measure. RESULTS Ankle stress radiographic interobserver agreement was ICC = 0.73 to 0.97 for anterior talar drawer test and ICC = 0.78 to 0.97 for talar tilt. Interobserver reliability for calcaneocuboid angle measurement methods was lower (ICC = 0.35-0.91) than for the calcaneocuboid joint-space distance measurements (ICC = 0.81-0.95). Intraobserver ICC varied between 0.78 and 0.97 for ankle stress testing and was 0.67 to 0.94 for calcaneocuboid stress radiography, respectively. CONCLUSIONS Ankle stress radiographic measurements were proven to be reliable. Insufficient reproducibility was found for angular calcaneocuboid stress radiography measurements, while lateral calcaneocuboid joint-space distances offered accurate reliability. CLINICAL RELEVANCE Measurement errors can be avoided using standardized stress radiography and measurement techniques with proven reliability.

Abstract
OBJECTIVE In contrast to posterior tibial tendon lesions, dislocations of the posterior tibial tendon are thought to be 'extremely rare'. Diagnostic criteria for this condition have not yet been established. METHODS A systematic literature review revealed 61 published cases with posterior tibial tendon dislocation in 36 reports, including eight (12 patients) in French and five (7 patients) in German. We add one more case, which was complicated by a longitudinal tibial tendon tear and a lateral talar dome osteochondral lesion. Fifty-nine cases were descriptively analysed regarding initial injury, subjective symptoms, clinical presentation and findings on different imaging modalities. Treatment and outcome were additionally evaluated. RESULTS 58.5% of the initial injuries were induced by sport. Initially most cases were misdiagnosed (53.1%). 35.6% of the patients felt a recurrent snapping phenomenon at the medial ankle. Physical examination exhibited a cord-like structure over the medial malleolus in 58.6%, and a posterior tibial tendon (sub)luxation could be provocated in 54.2%. MRI, ultrasound and plain radiography (medial malleolar chip fracture) detected specific findings in 75.0%, 66.7% and 14.7%, respectively. Surgery was done in 83.1% of the patients using varying techniques. The authors judged the treatment result as excellent or asymptomatic in 80%, as good in 12% and as fair or moderate in 8% of the patients. CONCLUSIONS Posterior tibial tendon dislocation occurs more frequently than was previously thought. Misdiagnosis can be avoided, if the surgeon is aware of the condition and combines findings from history, physical investigation and imaging modalities.

Abstract
BACKGROUND Endoscopic treatment of intractable chronic anterior and lateral exertional compartment syndromes of the lower leg in athletes is reported anecdotically only in six patients. HYPOTHESIS H(0) = There is no difference between preoperative and postoperative status after endoscopic release of chronic exertional compartment syndromes of the lower leg. STUDY DESIGN Case series; level of evidence, 4. METHODS We developed a minimally invasive, endoscopically assisted technique for release of chronic exertional compartment syndromes of the lower leg. All patients were investigated by telephone interview 47 months (range 5 months-7 years) after surgery. RESULTS This investigation comprises release of 19 deep posterior, 16 anterior, and 3 lateral compartments in 17 athletes. No complications were seen following endoscopic anterior and lateral compartment decompression, while two patients following deep posterior compartment release underwent open revision surgery due to hemorrhage. Initial endoscopic surgery in these two patients was performed under tourniquet. There were no postoperative complications due to vascular injuries in all further patients who were operated without tourniquet. Ten patients returned to previous sport activity. At follow-up, results were good or excellent in 10 out of 17 patients. Visual analogue pain scale ranged from 5 to 9 (mean 7.4) before surgery and from 1 to 8 (mean 2.4) at follow up (P = 0.0005). CONCLUSIONS This study confirms feasibility of endoscopic release for chronic exertional compartment syndromes of the lower leg on a larger scale. At least for the deep posterior compartment its safety and effectiveness cannot be recommended without stint as results are inferior as compared to data obtained from literature for open surgery. To avoid vascular complications, especially during deep posterior compartment fasciotomy it is most important to perform the procedure without tourniquet.

Abstract
BACKGROUND Isolated lateral calcaneocuboid joint instability rarely is described. Missed or delayed diagnosis resulting in inadequate treatment may lead to chronic instability, followed by sports inability and handicap in daily life. Besides arthrodesis, anatomic repair augmenting the elongated dorsal calcaneocuboid ligament with a local periosteal flap has recently been described for treatment. METHODS In a controlled laboratory study, eight isolated fresh-frozen human cadaver calcaneocuboid specimens were strained in a varus direction until failure of the dorsal calcaneocuboid ligaments. Then the dorsal calcaneocuboid ligaments were reconstructed with free periosteal flaps and tensile testing was repeated. RESULTS Compared to native dorsal calcaneocuboid ligaments, free single layer periosteal flap reconstructions were found to have inferior load to failure (-52%, p = 0,028), ultimate stress (-44%, p = 0.024), stiffness (-50%, p = 0.063), and strain energy density to failure (-37.5%, p = 0.111). CONCLUSIONS In vitro data demonstrate that isolated single-layer periosteal flap replacement offers inferior stability as compared to native dorsal calcaneocuboid ligaments. To obtain sufficient initial stability, the elongated native ligament should, therefore, be reefed and a single-layer periosteal flap augmentation should be added. This combined procedure can be recommended for stabilization of isolated chronic dorsolateral calcaneocuboid joint instability.

Abstract
OBJECTIVE Anatomic reconstruction is the treatment of choice for lateral ankle ligament instability. A similar technique has recently been described for stabilisation of a chronic unstable calcaneocuboid joint as an alternative to the previously proposed tenodesis and arthrodesis procedures. METHODS Five consecutive young females experiencing recurrent giving way of six calcaneocuboid joints were treated operatively during a 4 year period using anatomic ligament repair reinforced by a periosteal flap. Results were compared to five patients who underwent anatomic lateral ankle ligament repair in a case-control design. Outcome was measured using the Foot and Ankle Outcome Score, physical examination, and stress radiographic and MRI (calcaneocuboid group) investigation. Functional neuromuscular performance was evaluated by isokinetic torque measurements, posturometry, single-leg drop jumps, and single-leg long jumps. RESULTS Outcome scores at follow up (5-61 months after surgery) revealed excellent results for both groups. No relevant difference was found between the affected legs and the non-affected legs or between groups with respect to the outcome measures. MRI exhibited ligament-like structures at the repaired dorsal calcaneocuboid joints in five out of six joints. CONCLUSIONS Results of anatomic repair of unstable lateral ankle and isolated calcaneocuboid joint instability equally lead to excellent results.

Abstract
BACKGROUND About half of patients who have Haglund disease may require treatment by surgical resection of the superior portion of the calcaneal tuberosity. Endoscopic techniques have been described as alternatives to open surgery, but only results of uncontrolled retrospective clinical investigations have been reported. Up to now no research is available which compares these different procedures. METHODS A controlled laboratory study was done to evaluate the morphologic appearance of the superior portion of the calcaneal tuberosity after endoscopic or open resection. The tuberosity was resected in 15 isolated fresh-frozen human cadaver lower limb specimens with either open (nine) or endoscopic (six) technique. Outcome was measured radiographically. Iatrogenic soft-tissue lesions of the distal Achilles tendon, plantaris tendon and sural nerve caused by the surgical procedure were evaluated by direct observation after anatomic dissection. RESULTS Radiographs revealed that the slope of the resection line (osteotomy angle) was steeper (p = 0.017) and the resected protruberance was larger (p = 0.003), while the remaining posterior rim was smaller (p = 0.048) after open resection than after endoscopic resection. Macroscopic analysis indicated that both approaches may damage soft tissues particularly the medial Achilles tendon column and in the plantaris tendon (relative risk = 0.5 in either group). Iatrogenic sural nerve injuries were found after both techniques (relative risk = 0.2 for endoscopic and 0.1 for open resection). Residual bursa tissue was detected only after endoscopy (relative risk = 0.3), while loose bony fragments were present only after open surgery (relative risk = 0.4). CONCLUSIONS AND CLINICAL RELEVANCE The medial column of the Achilles tendon, the plantaris tendon, and the sural nerve are at risk in both open and endoscopic resection for Haglund disease.
